C0695 Position Sensor Overcurrent (8 volt supply)

Definition

Common causes

• Shorted position sensor wiring
• Faulty position sensor
• Open circuit in the sensor supply line
• Poor ground connection
• Malfunctioning powertrain control module (PCM)
• Corroded or damaged connectors
• Overloaded circuit due to additional components
• Faulty voltage regulator or power supply issues

Common misdiagnoses

• Faulty position sensor
• Wiring issues or shorts
• Malfunctioning power supply or voltage regulator
• ECU (Engine Control Unit) failure
• Grounding problems
• Connector issues or corrosion
• Other sensor failures (e.g., throttle position sensor)
• Software or calibration errors in the ECU

Troubleshooting steps

1. 1. Understand the Code

   C0695 typically relates to a problem with a position sensor that operates on an 8-volt supply. This could be related to sensors like throttle position sensors, pedal position sensors, or other similar components

2. 2. Check for Additional Codes

   Use an OBD-II scanner to check for any other related trouble codes. This can provide more context and help identify if there are multiple issues

3. 3. Inspect Wiring and Connectors

   Visual Inspection: Look for damaged, frayed, or corroded wiring and connectors associated with the position sensor

4. 4. Connector Integrity

   Ensure that all connectors are securely attached and free of dirt or corrosion

5. 5. Test the Position Sensor

   Resistance Check: Use a multimeter to measure the resistance of the position sensor. Compare the readings to the manufacturer’s specifications

6. 6. Voltage Check

   With the ignition on (engine off), check the voltage at the sensor connector. Ensure it is receiving the correct voltage (around 8 volts)

7. 7. Signal Check

   If applicable, check the signal output from the sensor while moving the sensor through its range of motion

8. 8. Check the Power Supply

   Voltage Supply: Verify that the 8-volt supply is present at the sensor connector. If not, trace back to the power source to identify any issues

9. 9. Ground Connection

   Ensure that the ground connection for the sensor is solid and free of corrosion

10. 10. Inspect the Control Module

    If the sensor and wiring appear to be in good condition, the issue may lie within the control module (ECU). Check for any software updates or known issues with the module

11. 11. Look for Short Circuits

    Inspect the wiring harness for any signs of short circuits or grounding issues that could cause an overcurrent condition

12. 12. Check for Mechanical Issues

    If the position sensor is part of a mechanical assembly (like a throttle body), ensure that there are no mechanical obstructions or binding that could affect the sensor's operation

13. 13. Clear Codes and Test Drive

    After performing the checks and repairs, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns

14. 14. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the specific make and model of the vehicle, as there may be known issues or recalls that address the problem.1

15. 15. Seek Professional Help

    If the issue persists after following these steps, it may be necessary to consult a professional mechanic or technician who has access to specialized diagnostic tools and equipment. By following these troubleshooting steps, you should be able to identify the root cause of the C0695 code and take appropriate action to resolve the issue
